Summary
Algae are vital wetland ecosystem players, functioning as primary producers and nutrient cyclers. Further research is needed to understand environmental controls on algae and their role in food webs.
Area of Science:
- Wetland ecology
- Algal biology
- Ecosystem function
Context:
- Wetlands host diverse algae, including epipelon, epiphyton, metaphyton, and phytoplankton.
- Diatoms, green algae, and blue-green algae are dominant species in wetland environments.
- Algae are integral to wetland physical, chemical, and biological processes.
Purpose:
- To review advancements in algae ecology within wetland ecosystems.
- To explore algae's population structure, function, and productivity.
- To identify factors influencing algal productivity and their ecological roles.
Summary:
- Algae are fundamental in wetland ecosystems, acting as primary producers and contributing to food webs and nutrient cycling.
- They serve as food for herbivores and sources of dissolved organic matter and nitrogen.
- Algae can also function as biomarkers for environmental pollution monitoring.
- Factors influencing algal productivity include hydraulics, nutrition, temperature, light, and grazing pressure.
Impact:
- Highlights the critical roles of algae in wetland ecosystems, from primary production to nutrient cycling.
- Emphasizes algae's utility as environmental pollution biomarkers.
- Recommends future research directions, including evaluating contributions of different algal assemblages to food webs and exploring genetic techniques for managing harmful algal blooms.
